Stay away from Parrot bluetooth
I have two parrot handsfree units, CK3200LS in my car, CK3100 in my wifes.
They have caused nothing but trouble for my WM phones (Tilt and now TP2)
I can't get the TP2 to pair with the CK3100. I'm waiting for parrot to respond to my help request. Their support info is worthless. The instructions refer to settings which don't exist and password format which is unusable (/"1234/" ?).
When the WM phones successfully pair, there is a re-occuring problem in both Parrot units where there appears to be an incoming call (it doesn't show a caller ID - just 'CALL') but the call cannot be answered. If you press the green button to answer, the unit locks up. You can't "disconnect" with the red button. The only thing you can do, is turn the car off, wait for the unit to turn off, and then turn the car back on to reset. Sometimes my Tilt would get locked up from the call and need to be soft-reset as well.
I had the unit working successfully with non-WM phones for some time, so it was no longer under warranty. When it started with the WM phones I took it to the installer. He was aware of the problem, but had no idea how to deal with it as the problem is so transient.
Bottom line - stay away from Parrot if you have a WM phone.
